Abstract
In order to resolve problems of inconvenient workpiece clamping and poor detecting precision caused by a cylindrical positioning pin in the prior art, the utility model provides a positioning detection tool. A bottom seat of the detection tool is arranged under a pedestal and is connected with the pedestal. A shaft sleeve is inserted into installing holes on the pedestal and the bottom seat. A first bearing and a second bearing are supported and fixed between the shaft sleeve and the pedestal. A radial protrusion is disposed on the top of the shaft sleeve. An abutting relation is formed between the bottom of the radial protrusion and the top of the first bearing. An end cap is disposed on the radical protrusion of the shaft sleeve and is connected with the pedestal. A positioning pin is arranged over the end cap and is sleeved on an expansion mandrel. The top of the expansion mandrel is in an inverse taper shape. A cylinder is disposed under the bottom seat and is connected with the bottom seat. The positioning detection tool has beneficial effects that when detected by the positioning detection tool, the workpiece is not required to be installed and uninstalled such that the positioning detection tool is convenient and easy to manipulate and has greatly-increased detecting efficiency, that the cylinder drives a pull bar such that the positioning pin is expanded to achieve positioning, and that the poisoning pin cannot be abraded so as to increase positioning precision and decrease positioning errors.
Description
Technical field
The utility model relates to cubing technical field, specially refers to a kind of locating check fixture.
Background technology
The position degree that prior art comprehensive check tool detects workpiece is all to adopt cylindrical positioning pins, adopt cylindrical positioning pins detection position to be positioned with following drawback: first, the clamping on comprehensive check tool of workpiece is inconvenient, need to manually load and unload, when the volume and weight of workpiece is large, aobvious inefficiency especially.The second, with cylindrical positioning pins, in the process of frequent workpiece loading and unloading, can there are straight pin wearing and tearing, thereby cause positioning error large, to the detection error of workpiece also just greatly, even lose the meaning of the detection of cylindrical positioning pins.Obviously, prior art exists the problems such as clamping workpiece is inconvenient and accuracy of detection is poor.
Utility model content
The clamping workpiece inconvenience and the poor problem of accuracy of detection that in order to solve prior art, exist, the utility model proposes a kind of locating check fixture.
The utility model locating check fixture, this cubing comprises cylinder, expanding arbor, register pin, end cap, clutch shaft bearing, the second bearing, base, axle sleeve and pedestal, described base is positioned at pedestal below and is connected with pedestal, in the mounting hole of axle sleeve injection pedestal and base, between axle sleeve and pedestal, be provided with clutch shaft bearing and the second bearings is fixed, axle sleeve upper end is provided with radial protrusion, below radial protrusion, form against relation with clutch shaft bearing upper end, end cap is arranged on above the radial protrusion of axle sleeve and is connected with pedestal, register pin is positioned at end cap top and is sleeved on expanding arbor, expanding arbor upper end is back taper, cylinder is positioned at base below and is connected with base.
Further, end cap two ends are equipped with radial protrusion, and with screw, are connected with pedestal on radial protrusion.
Further, base is provided with upwards axial projection, and axial projection is inserted in pedestal, forms interference and connects.
Axial projection and the second bearing lower end of further, on base, inserting in pedestal form against relation.
Further, the diameter of the lower end of base is identical with cylinder bore.
Further, in cylinder, be provided with pull bar.
The beneficial effect of the utility model locating check fixture is when detecting workpiece, and without workpiece loading and unloading, easy to operate simple, detection efficiency promotes greatly.Because cylinder drives pull bar, register pin is expanded and locate, register pin can not wear and tear, and positioning precision is improved, and has reduced positioning error.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the utility model locating check fixture;
Below in conjunction with the drawings and specific embodiments to the utility model locating check fixture further instruction.
Embodiment
Accompanying drawing 1 is the structural representation of the utility model locating check fixture, and in figure, 1 is pedestal, and 2 is register pin, and 3 is end cap, and 4 is clutch shaft bearing, and 5 is the second bearing, and 6 is cylinder, and 7 is pull bar, and 8 is base, and 9 is expanding arbor, and 10 is axle sleeve.As seen from the figure, the cylinder 6 of the utility model locating check fixture is positioned at the below of base 8, the diameter of base 8 lower ends and cylinder 6 identical with the diameter of cylinder 6 is affixed merga pass inner bolt with base 8 and is connected, axle sleeve 10 is applied in the mounting hole of pedestal 1, is provided with clutch shaft bearing 4 and the second bearing 5 and supports fixing between axle sleeve 10 and pedestal 1.Axle sleeve 10 upper ends are provided with radial protrusion, form against relation below radial protrusion with clutch shaft bearing 4 upper ends; End cap 3 lids are pressed on the radial protrusion of axle sleeve 10, and end cap 3 two ends are provided with radial protrusion, and with screw, are connected with pedestal 1 on radial protrusion, expanding arbor 9 is inserted in axle sleeve 10, expanding arbor 10 upper ends are back taper, and pull bar 7 is arranged in cylinder 6, by cylinder 6, is driven.Base 8 is provided with upwards axial projection, and axial projection is inserted in pedestal 1, forms interference and connects.The second bearing 5 lower ends form against relation with the axial projection of inserting on base 6 in pedestal 1.Register pin 2 is positioned at end cap 3 tops and is enclosed within on expanding arbor 9.To be cylinder 6 can be converted into mechanical energy by air pressure to the course of work of the utility model locating check fixture drives pull bar 7 to move up and down, pull bar 7 is by the interaction relation with expanding arbor 9 formation, drive expanding arbor 9, expanding arbor 9 is in descending process, because the large end of structure of tapering point is descending, described register pin 2 is expanded, accurately locate.When expanding arbor 9 is up, because the large end of structure of tapering point is up, register pin 2 is resetted.Such locator meams is convenient and swift, and accurately, error is little.
The beneficial effect of the utility model locating check fixture is when detecting workpiece, and without workpiece loading and unloading, easy to operate simple, detection efficiency promotes greatly.Because cylinder drives pull bar, register pin is expanded and locate, register pin can not wear and tear, and positioning precision is improved, and has reduced positioning error.
Although the utility model is described with reference to an explanatory embodiment of the present utility model here, but, should be appreciated that, those skilled in the art can design a lot of other modification and embodiments, and these are revised and within embodiment will drop on the disclosed principle scope and spirit of the application.More particularly, in the scope of, accompanying drawing open in the application and claim, can carry out multiple modification and improvement to the building block of subject combination layout and/or layout.Except modification that building block and/or layout are carried out with improving, to those skilled in the art, other purposes will be also obvious.
